Metal Free Algaecide will help control algae without introducing metal ions.
Algae are relatively harmless to humans but they may make the pool unsightly, may cause colours, promote bacterial growth, assist in the formation of chloramines and their presence indicates poor pool maintenance. From a safety point of view algae cause slippery pool walls, pool bottoms and walkways. Algae can be introduced into a pool in the form of airborne spores, blowing free in the air attached to dust or enveloped by raindrops. They are mainly associated with outdoor pools as they require sunlight to grow. The most uniformly accepted algal control procedure is to maintain a free chlorine residual of between 1 to 2 mg/L or where pools are warmer than 26 C a minimum 3 mg/L concentration. There is a range of algaecides available and their compatibility with the disinfectant system should be determined at the point of sale. Algaecides are an adjunct to pool conditioning for winter. Pool owners should know that the use of algaecide can prevent all known varieties of algae.
WHAT TYPES OF ALGAE ARE THERE?
There are over 21,000 known varieties of algae! In the pool business we avoid all of the complication by referring to algae by the color they exhibit.
GREEN ALGAE: An extremely common variety, green algae will usually rear its ugly head immediately following a hazy condition in the water from a lack of proper filtration and/or sanitation. It is frequently found free floating in the water, although it also will cling to the walls. It reduces water clarity and is thereby distinguished from severe copper precipitation, which will impart a clear, green color to the water. Varieties of green algae also appear as "spots" on surfaces, particularly rough areas, or places where circulation is low. They also show up as "sheets", where large wall sections, or even the entire pool, is coated in green slime...UGH! Hit it hard! with Shock it and Concentrated Algaecide. Prevention can be acomplisded : Use Weekly algaecide.
YELLOW ALGAE: A wall clinging variety, also called mustard algae, is usually found on the shady side of the pool. It is sheet forming, and can be difficult to eradicate completely. Once begun, a pool owner could spend the entire season fighting yellow algae; reinfection is common. This variety is resistant to normal chlorine levels and must be dealt with firmly. Hit it hard! with Shock it. Prevention can be acomplisded : Use Weekly algaecide.
BLACK ALGAE: Perhaps the most aggravating strain of algae, it has been compared to herpes; "once you've got it, it's there for life". This is not entirely accurate, but the difficulty in eradication is due to the strong roots and protective layers over top of the black algae plant. Black algae will appear as dark black or blue/green spots, usually the size of a pencil eraser tip. Their roots extend into the plaster or tile grout, and unless the roots are destroyed completely, a new head will grow back in the same place. The heads also contain protective layers to keep cell destroying chemicals from entering the organism. Like yellow algae, black strains can bloom even in the presence of normal sanitizing levels and proper filtration.
